SECTION 2: Hazards identification

Hazard Data: Low concentrations of crystalline silica (Si02) in the form of quartz, cristobalite or tridymite may be present. Health 1 Flammability 0 Reactivity 0 Ratings based on NPFA IARC Overall Evaluation: Inhaled crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1). The OSHA Permissible Exposure Limits from Table Z-3 Mineral Dusts are: Crystalline Silica Quartz (Respirable) 10 mg/m3 %SiO2+2 Quartz (Total Dust) 30 mg/m3 %SiO2+2 If cristobalite or tridymite is detected, use one half the values calculated from formulae for quartz. Inhalation: Acute: Breathing silica dust may cause irritation of the nose, throat and respiratory passages. Chronic: Breathing silica dust may not cause noticeable injury to illness even though permanent lung damage may be occurring. Inhalation of dust may also cause silicosis. Cancer Status: The International Agency for Research on Cancer (IARC) has determined that crystalline silica inhaled n the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1 – carcinogenic to humans). The National Toxicology Program (NTP) classifies respirable crystalline silica as “known to be a human carcinogen”. The American Conference of Governmental Industrial Hygienists (ACGIH) classified crystalline silica, quartz, as a suspected human carcinogen (A2). Skin Contact: May be severely irritating to the skin Eye Contact: May be severely irritating to the eyes. Ingestion: Not anticipated route of exposure. May cause gastric distress, nausea and vomiting if ingested.

Medical Conditions Generally Aggravated by Exposure

Individuals with respiratory disease, including but not limited to asthma, emphysema and bronchitis, or subject to eye irritation should not be exposed to respirable dust.
